An. auxi1iary .umtnzn; and.v pnoy nded int rier is secured rigidly tothe lower open ends of the faucets l and I 2. This securement isefiected, at the upper ends of two laterally outwardly and then upwardlydirected branch conduit portions 2| and 22, by means, in the case ofeach faucet. comprising a pair of clamp rings 23 and 24 and threetie-bolts 25. Said rings are matchingly aperturedwith such apertures 120apart, for taking said bolts; and there is interposed between each of"the faucets and the associated conduit portion 2! and 22 a gasket 26.

The inner ends of the conduit portions 2| and 9,575,368 .ilg ci 'flf J3... 5: 1. 1

dle section 44 may be turned relative to the handle section 43, therebyto turn the rod 45 to fractionally rotate the cam entity 49 and so raiseor lower the valve member 31. As the'parts are shown, the valve member3| is fully lowered, shutting off any water discharge at the deliveryfaucet 29. When said valve member is fully raised, the fullpredetermined water pressure will be established at the faucet'29; whichpressure maybe modified as desired according to how much said valve israised or lowered.

22 meet the lower end of a vertically upstanding conduit portion 2'! andthe upper end of a downwardly extending short conduit element 28 forming the upper subdivision of a delivery faucet 29 extending forwardly asshown in Fig.2 andthen downwardly as shown in Figs. 1, 2 and 4.

The shut-off and pressure control vnv'ep'm vided includes a valve seat30, and a cylindrical valve member 3| fixed on the lowerend ofavertically 'endwisely movable rod 32. This rod extends up through theconduit portion 21' and through a screw-cap 33 for said conduit portion,for projection above said cap. At its top the rod 32 is formed toprovide a ball 34. A bushing 31 is screw-threadedly secured in the cap33; and said bushing serves to embrace the upper portion of the rod 32to permit easy'up and down endwise movement thereof, and also acts as ajournalling means for a spur gear 35 meshing with the two spur pinionsl9. Said gear 35 is held in mesh with the pinions l9 by an annularflange 36 carried exteriorly at the top of the bushing 31, as thepinions l9 rise an'clfall during lifting'and lowering of the valves l5and 15.

A single swing-arm actuator 38 is provided and includes a tube 39 fixednear its inner end in a bracket 45 secured-as at 4! to the gear 35. Onthe outer end of said tube is fixed, as at 42; a handle section 43.Beyond the outer face of the latter, the tube 39 extends into anotherhandle section 44. Rotatable in the tube 39 is a rod. with its outer endpinned as at 46 to the handle section 44. The inner end of the tube 39is re' duced in external diameter as at 41. i

The ball 34 is a cam follower relative to a cam groove 48 partiallyformed in each of two members of like construction except for a hubportion carried by one of them, but of" opposite hand; said'membersbeing shaped and'coupled to provide acam entity 45 for presenting saidgroove. The said cam entity is rotatively mounted as shown on thereduced inner end portion 41 of the tube 39; and is fixed to the innerend of the rod 45, as by means of a cotter pin '50 sent through the rodand also through the hub portion'of that one of said membersconstituting the left half, as viewed in Fig. l, of the cam entity 49.

Fig. 4 illustrates a casing 5|, which may be used to enclose theentirety of the fixture, except for the handle-carrying end of theactuator '38,'and except for the delivery faucet 25. At the front of thecasing is a long horizontally extending slot 52, through which saidactuator projects: and along which it is movableto causerotationof thegear 35 in one direction or the other through somewhat less than 180 Aportion of the bot tom wall of the casing 5| is shown in-Fig. 1, thiswall having an opening 53 for protrusion of the delivery faucet as shownin Figs. 1 andl.

Operation In any angular adjustment of the actuator 38 The actuator 38has an angular swing about the axisof .therod 32 as a center, throughsubstantially thereby to rotate the gear 35 through substantially a halfrevolution in one direction or the other; said actuator being shown inFigs-l and 2 at we limit of its said swing. The

ratio of the pinions I9 to the gear 35 is one to three. Therefore, oneach half revolution of the gear 35, both pinions will rotate throughone and one-half revolutions, and so each of the. valve members 45 andiii-will be rotated through one and one-half revolutions.

Because of the already describedthreadedconnection l5''-l 5" between thevalve 'member" 15 and-the faucet l5 and the already described threadedconnection IBI5"- between the valve member 16 and the faucet it, onswinging the actuator 38 to its pcsitionshown in Fig. 1 from itsotherlimit of swing, that is, from its position indicated in dot and dashlines at 38 in Fig. 1, the valve member l5 will be spirally raised 'tofully open conditionand the valve member I6 willbe spirally lowered tofully'close'd condition; as shown in Fig. -1. Similarly, on'swinging theactuator 38 from its position shown in Fig. 'l' to its positionindicated at 33 in that view',-'the valve member 16 will be spirallyraised to fully open condition and the valve member 15 will-be spirallylowered to fully closed condition. Similarly, also,'on swinging theactuator 33 to cause the same *to extend as indicated in dot and dashlines at 38 in Fig. 2, both of the valve members I 5 and-I5 will be inhalf open condition, Thus, according as the actuator 38 is'swung intothe selected one of a multitude of different positions, over a swing ofthe actuator through substantially 180, precisely-the desired mixtureof-hqt and cold water may be obtained atthe faucet 29.

While we have illustrated and described the preferred embodiment of ourinvention, it is to be understood that we donot limit ourselves to theprecise constructions herein disclosed'and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims. 7 7 q Having thus described ourinvention, what we claim as new, and desire-to secure by United StatesLetters Patent isz 1.
